Modular manifolds add NPT tapers for water-tight sealsModular manifolds add NPT tapers for water-tight seals

Anaheim, CA—On the market for three years, Kool Flow has sold "thousands" of its Flex Block Series manifolds, according to company President Ron Seabolt, who told PlasticsToday at Plastec West 2013 that Kool Flow had entered into a new relationships with mold component supplier, PCS.

New at the show was a series with NPT (national pipe thread) tapers for the manifold, including under/over tightening fittings. PCS points out that unlike straight threads, taper threads will pull snug and therefore make a fluid-tight seal.

Instead of pipe tape sealing water-line connections, Seabolt said an o-ring seal on the taper will create a tight seal that can be oriented in any direction. With the FP3 series (1.5-inch inlet and 3/8 to .5 inch outlet), molders can detach the water line at the hose. Ultimately, Seabolt said he also wants to make manifold assembly more efficient for distributors, like PCS. Now Kool Flow offers a 2-inch 2-station tie rod kit that he says will reduce cost and time to assemble.

The manifolds are machined from 6061 billet aluminum, which holds tighter tolerances. Kool Flow Flex Block Series manifolds, are also available now with a 90° inlet block. In addition to the FB3 Series, there is the FB2 Series (1-inch inlet and .25 to 3/8 inch outlet). The manifolds have offset porting, which allows more clearance for wrenches and tools.
